COPYING APPARATUS.

SPECIFICATION formingpart of Letters Patent No. 627,636, dated June 27, 1899. i

To aZZ whom it may concern:

Be it known that 1, JAMES GEORGE BECK- TON, a subject of the Queen of England, residing at Middlesbrough, England, have invented certain new and useful Improvements in or Relati ng to Copying Apparatus, of which the following is a specification.

This invention relates to copying apparatus by which facsimile or other copies can be obtained of letters or other documents, drawings, &c., in single sheets and may be carried out in the following manner.

I provide any suitable box, frame, or th like, and upon this I have a sheet or table, upon which the document to be copied or to receive the impression is placed. The frame is provided with grooves or guides for controlling the movement of a roller which is caused to reciprocateacross the surface of the the paper, &c., to receive it or to press the paper onto the gelatin or other sheet, or the roller may be of a circumference equal, substantially, to the length of the gelatin or other copy-bearing sheet, which may be wrapped around it, so that as the roller traverses the paper below an impression will be obtained. The guides may be provided with springs or other means of applying pressure to the roller.

Upon the frame are pivoted slotted arms, in the slots of which the ends of the roller or extensions thereof or the spindle which carries the roller are placed after passing through the previously-mentioned slots or guides of the frame. It willth us be understood that as the arms or the handle which connects them are moved backward and forward the roller is caused to traverse the surface of the table, thus obtaining the impressions, as already explained.

The end of the roller or the spindle may be provided with a projection, cam, or equivalent or may engage with a cam or the like for the purpose of lifting it at any desired portion of the traverse clear of the paper, due.

The same apparatus may be employed for obtaining an indefinite number of copies, if

the roller carries a suitable impression, and is caused to traverse a slab or plate containing Application filed December 20, 1897. Serial No. 662,668. (No model.)

printers ink or other coloring-matter first and then the paper or materialupon or through which the impression is to be obtained. In this case the previously-mentioned table may be extended or a separate table provided for the ink or color and the arms and other parts of the apparatus arranged to impart the neoessary'length of travel to the roller,

The endsof the roller or spindle may be carried in sliding blocks, ball or roller bearings, or equivalent devices to reduce friction.

In the accompanying drawings, Figure 1 is an elevation of one form of the apparatus. Fig. 2 is a plan of the same. Fig. 3 is an elevation of a modification. Fig. 4 is a plan of the same. Fig. 5 is a cross-section showing a'modification of the guide-bar construct-ion.

Asuitable box orframeAis provided, having upon it a sheet or table A. At the sides of the box are pivoted at B two levers 0, slot ted, as at D. Through these slots pass the ends of a spindle E, carryingarollerF. The

roller is prevented from being lifted from the may or may not be made of gelatin) on the table A, over it the sheet to receive the impression, and then passing the roller over both, or the circumference of the roller may be approximately equal to the length of the table, as shown in Figs. 1 and 2. In this case I prefer to fix the reproducing substance on the roller, placing the sheet on the table A. In the former case the table and in the latter the roller is covered with felt or other suitable material in order to provide a yielding surface. Gelatin may be used for this pur pose.

In order to enable the roller F to be adj usted so as to exert upon the surface of the table A the pressure necessary for copying, the guide-bars H are provided at theirends with screws N. Springs 0 may, if desired, be combined with or take the place of the screws N.

Instead of reciprocating the roller F indirectly by the levers C it may be done directly bya handle L, which is connected to the spindle E by a suitable metal or other frame M, as shown in Figs. 3 and 4. In this case single guide-bars are used, passing through holes in blocks J on the spindle E, as shown in Figs. 3 and 4, when the guide-bars may be of any cross-section, but preferably round.

In place of the guide-blocks J rollers J such as shown in Fig. 5, may be employed, upon which the adjustable guide-bars II exert their pressure.

I claim 1. In a copying apparatus, the combination with a table or bed, of guide-bars arranged longitudinally of the table, one at each side thereof, and adapted for vertical movement relatively to the table, means yieldinglysupporting the said guide-bars, a roller arranged transversely of and above the table, a spindle for said roller, and means slidingly con- I necting the ends of said spindle with the guide-bars.

2. In a copying apparatus, the combination with a table or bed, of guide-bars arranged longitudinally of the table, one at each side thereof, uprights on the table with which the guide-bars are slidingly connected to adapt the latter for vertical movement, springs supporting the guide-bars at their ends, a roller arranged transversely of and above the table, a spindle for said roller and means slidingly connecting the ends of the spindle with the guide-bars and a handle for reciprocatingthe roller.

In testimony whereof I have hereto set my hand in the presence of the two subscribing witnesses.

JAMES GEORGE BECKTON.
